In this case, we describe a patient with a history of recurrent pneumothorax. Based on CT-thorax and histopathology of the lung tissue, the Birt-Hogg-Dubé syndrome was suspected and confirmed after genetic testing. Recognizing this syndrome by pulmonologists and radiologists is very important, because the risk on developing of renal cell cancer is high.

Fractional exhaled nitric oxide (FENO) measurements are recommended for the assessment of eosinophilic airway inflammation in asthma. Clinically relevant increases in FENO have been reported 24 h after positive specific inhalational challenge (SIC) tests in occupational asthma. We aimed to determine whether positive SICs could be discriminated from control tests, on the basis of change in FENO. ⋯ FENO changes above the upper confidence limits of ≥20 % or ≥6 ppb may be considered to be outside the range of normality. However, the majority of workers who had clearly positive SICs to common low molecular weight agents also had no statistically or clinically relevant increase in FENO. Therefore, change in FENO does not predict a positive SIC in this group.

Protein-protein interaction network analysis in chronic obstructive pulmonary disease.
The aim of this study was to investigate the gene expression profile of chronic obstructive pulmonary disease (COPD) patients and non-COPD patients. ⋯ Comprehensive analysis of the gene expression profile for COPD versus control reveals helveticoside, disulfiram, and lanatoside C as potential molecular targets in COPD. This evidence provides a new breakthrough in the medical treatment of patients with COPD.
